ROTARY SPINNING-RING AND ADJUSTABLE HOLDER THEREFOR.

Specification of Letters Patent. 1

Patented May 1 1, 1909.

Application filed. Ma a, 1907, Serial m. 371,865.

To all whom it may concern:

Be it known that I, JAMEs A. WALTON, a citizen of the United States, residing at Taunton, in the county of Bristol and State 5 of Massachusetts, have invented certain new and useful Improvements in Rotary Spinning-Rings and Adjustable Holders Therefor, of which the following is a specification.

My invention relates to spinning rings and holders therefor employed in the spinning and twisting of fibers and threads, and part cularly to such apparatus in which the rmgs rotate as the spindles with which they are used revolve. I It is now customary to provide holders in special sizes to receive and fit each size ring employed in spinning, that'is, a holderof the proper size for each size ring. This adds greatly to the cost of the holders and necessltates the carrying in stock of a largenumber of holders of each size. Moreover, holders for rotary rings, as heretofore constructed, have no means of adjustment to individual rings. In practice'I have found that these rings are not perfectly round, and on account of their warping and shrinking in the process of case-hardening, rings supposed to be of the same size will vary from one to sev eral hundredths of an inch from being true. As these rings must rotate in the holder at a high speed, it will be seen that perfect adustment of the holder to each individual ring is a necessity in order to secure the highest efficiency.

The spinning ring vided with two flanges, the lower flange restmg in the bearings of the holder as the ring rotates, and the upper flange carrying the traveler. In the practical use of such rotary rings, it has been-found. that, owing to the high speed at which both the ring and the traveler rotate, the lower flange becomes worn by friction with the bearings and the upper flange by friction of the traveler, so the ring soon becomes useless and must be re placed by a new one. These rings are not well balanced, and moreover, lint and dust rapidly accumulate on the traveler and in the bearings.

The principal object of my invention is to provide an adjustable holder for rotary spinnmg rings which will permit the use of as many sizes of rlngs as possible in one slze generally used is pro-- I holder, and allow for the proper adjustment of the holder to each individual ring.

A further object is to improve the construction of rotary spinning rings and provide a reversible ring with a bearing flange intermediate two traveler flanges and adapt ed to rotate in the bearings of the holder, which ring is, moreover, self-balancing and self-cleaning.

A further object is to improve the construction of the bearing posts which support the rotating ring.

These and other objects will more fully a pear as I proceed with the description of tie invention, of which a preferred embodiment is illustrated in the accompanying drawings, in which Figure 1 is a top plan view of my improved holder, with a rotary ring of my improved construction mounted in position; Fig. 2 is a central vertical section taken on the line 2-2 of Fig. 1, and showing the holder mounted upon a ring-rail; Fig. 3 is a detail 'in cross-section taken on line 33 of Fig. 1

Fig. 4 is a plan view of a modification, showing the holder adjustable but without the hinge; Fig. 5 is a side elevation showing a method of locking the armsof the holder in their adjusted position; and Figs. 6 and 6" are details showing a special construction of the bearing posts.

Referring to the drawings, I have shown the holder as having a base formed of arms A, A upon which are mounted bearing posts B, these latter being provided with bearings, which may be carefully machined slots as shown in Figs. 2 and 4, to receive a flange of the spinning ring. The arms are movable so as to permit of adjusting the bearings to a ring, and in the principal figures are shown as we in number pivoted upon a stud 0; upon which also is mounted one of the bearing posts. The base is substantially annular in outline and the free ends of the arms preferably overlap and are provided with guiding means consisting of a slot a formed in one of the arms and engaged by a projection a formed upon the other arm. It will be observed that'the slot a is slightly curved, preferably upon a metal of the arm. The arms are preferably formed from sheet metal and are suitably bent at a a adjacent the points where they overlie one another so that their main portions will lie flat upon the ring-rail.

It is the general custom to attach ring holders to the ring-rail by means of small screws passing through holes in the base of the holders. Wh en several sizes of holders are employed, this necessitates providing several sets of screw holes in the rail. To avoid this difficulty I provide slots in the base of my holder as shown at a a which extend preferably at an angle or transversely with respect to the arms of the holder, so that when the arms are moved toward or from each other for the purpose of adjusting the bearing posts for rings of different sizes or to allow for the variation of individual rings, the fastening screws o may still engage the same holes in the ringrail. These slots a, a are preferably slightly curved upon a radius having the pivot stud a as a center, so that in adjusting the holder it will still remain centered as a whole with respect to the spinning spindle.

i he arms or members A, A may be held in their adjusted position by means of the screws a by which they are fastened to the ring rail, and if desired may be provided also with a set-screw 0, as shown in Fig. 5 in place of the simple projection (1 Also, the slot (1 may be open at its outer end, as shown Fig. 5, instead of closed, as shown in Figs. 1 and 3.

Instead of the solid bearing posts B with their bearing slots Z), shown for the purpose of illustration, I may employ a special construction ofbearing posts, shown in Figs. 6 and 6* Here itwill be seen that the post comprises a sheet metal punching C formed up into an inverted U-shape, the ends 0 being turned outwardly and clamped under lugs b punched out and turned up upon the base member A. The ring may be seated in a bearing formed directly in this sheet metal post, or a bearing block 0 may be inserted within the post G and provided with a bearing slot 1), and clamped in this position by a lug 0 formed upon the top of the U-shaped post. It will be seen that the base ends 0 have an extended tongue underlying the lugs as indicated by dotted lines.

My improved ring D comprises an upper and a lower traveler flange d, (1 each extending across an end of the annular body of the ring. Intermediate these flanges, preferably midway, is a bearing flange (1 hich is shown as fiat and of greater width than the traveler flanges. This flange is also slightly thicker than the others, is preferably square at the edge, and engages the bearing slots of posts B. The width of the bearing flange d is such that when the ring is in position the lower flange d will clear the bearing posts, and the traveler moving around the upper flange (Z will just clear the top of the posts.

The use of my improved rotary ring and holder is obvious from the drawings and the foregoing description. Rings may be readily removed from and inserted in the holder by loosening or removing screws u. and spreading the arms A, TU. The movement of these arms upon their pivot permits of perfect adjustment to rings of different sizes, and also a fine adjustment to each individual ring which is an absolute necessity for securing the highest ollicieney of rotary rings. When the ringil) is seated with its bearing flange in the bearings of the posts, if no adjustment were possible to allow for the variations and defects of the individual rings, there would be binding or improper motions of certain rings causing trouble and delay in the entire spinning operation. Yfith a perfect adjustment for the holder to each individual ring, however, this variation in the rings is allowed for.

My novel form of rotary ring, both in itself and in combination with my adjustable holder, has several important admrntages. The ring is reversible, so that when one of the traveler flanges is worn by the traveler, the ring may be inverted and the other traveler flange used, thus n'olonging the life of the ring. Moreover, tie extended hearing flange serves to balance the ring during rotation, causing it to revolve more stea lily and thereby producing better yarn. lfurther, the centrifugai action and draft caused by the rapid rotation of the bearing flange, in addition to that of the other parts of the ring, blows away the fiber and dust from the bearings and prevents the latter from be coming clogged; and the tops of the beruing posts, being in close proximity to the moving traveler, act as traveler cleaners. lt will be seen, therefore that the ring is both selfbalancing and self-cleaning While I have described my holder as consisting of two arms, i do not wish to be understood as limiting the scope of the invention to that number. The holder may be composed of a single continuous strip, so that the arms are connected by a spring portion of the strip instead of by a hinge, this construction being shown in Fig. 4, or the number of arms may be varied without departing from the invention. Although l prefer my improved form of rotary ring, an ordinary ring may be used in my holder as indicated at D in Fig. 5. Also, it is not necessary to pivot the arms at one of the bearing posts, as this pivot may be located elsewhere, as shown in Fig. 6, and the exact position and number of the bearing posts may be varied.

Various other changes and modifications may be made without departing from the invention, and these i wish it understood fall strictly within the scope thereof Having described ,my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is
